How to restore a Server 2008 image backup to a new Hyper-V VM from NASMay 1st, 2009 by Linus
Acknowledgement: Thanks to Iain Jordinson from Windows Rescue in Queensland, Australia for finding this solution!
It is possible to restore an Server 2008 image backup to a Hyper-V VM, but unless you know this trick, you’ll receive this error:
An internal error occurred. The following information might help you resolve the error:
The network path was not found. (0x80070035)
To correctly restore an image backup to a new Hyper-V VM, do the following:
- Set up a new host for your machine
- Create a new VM from within the Hyper-V Manager console. Create a new virtual hard drive and make sure you set it to a size equal or greater than the hard drive of your old machine
- Before starting your new VM, go back to the Hyper-V Manager console, and edit the settings for this VM. Delete the existing network adapter, and add a Legacy Network Adapter Note: If you don’t do this, you’ll receive the error message described above.
- Insert the Windows disc in your DVD drive, capture it in your new VM and start the VM
- Perform the bare metal restore by choosing to Repair your computer, Complete PC Restore, then Cancel (to ignore the message that no backups could be found), Advanced, then Search for a network backup, and so on.
- The restore will start, and the computer will reboot when done.
Explanation: The regular Network Adapter in Hyper-V requires drivers under Server 2008, meaning that unless you have those drivers installed, you won’t be able to see the network. This means that the Windows Recovery Environment cannot use the network card, so you cannot do a bare-metal restore from a UNC path.
The Legacy Network Adapter can be used without drivers, so you can do a bare-metal restore from a UNC path.
My sincere thanks to Iain for figuring this out – after spending the better part of a day on the phone to Microsoft, who said that this could not be done. I’m confident that your efforts here will save many people countless hours of stress!
